The Williamson Line of 
Warm Air Furnaces 




IF there is anything in the way 
of warm air systems for the 
heating, ventilating and sanita- 
tion of buildings of all kind5 that 
interests you, this catalog comes 
with a fixed value greater than that 
of the ordinary catalog of houses 
manufacturing and installing such 
apparatus. It is only one of several 
different catalogs we publish, de- 
scribing various types of heating and 
ventilating apparatus made and sold 
by us. 

We have been engaged in the manu- 
facture of heating and ventilating 
equipment for more than thirty 
years. Through years of increasing 
success we have added valued ex- 
perience to growing asset s — 
experience that has enabled us to 
put upon the market furnaces of 
unequaled merit. 

The Williamson line of warm air furnaces, to which this catalog is de- 
voted, has been designed to meet every possible condition. Here will be 
found illustrated and described furnaces for different classes of build- 
ings, for different grades of fuel, and in sizes to meet every requirement. 

During the many years of our business experience our constant aim 
has been to make The Williamson Line the best possible to 
produce. That our efforts have been successful is proved by the 
fact that from a small beginning we have attained the position 
of the largest manufacturers of warm air heating and ventilating 
equipment in the United States. This enviable position has been 
reached solely through the superior merit of our product. Our constant 
aims have been to improve the quality of our furnaces in material, 
workmanship and design, and to furnish a better made article — 
one that will give better and more economical heating results and 
greater satisfaction than any other firm can furnish at the same or 
even higher cost. 

First-class work can only be turned out by first-class workmen, tools, 
materials and facilities. The talent we employ in all departments is 
the very best. Our Foundry is thoroughly equipped for manufacturing 

2

economically and well. Our castings are made of the best grade of 
gray iron castings, capable of withstanding successfully the strain of 
hard firing. It is possible for us to use a formula which produces 
furnace castings always uniform in quality, because our efforts are 
devoted exclusively to the manufacture of furnace castings, which 
results other concerns who make castings for commercial purposes as 
well, can not obtain. All castings are made on molding machines. 

Another feature of our organization to which we desire to call special 
attention is our Engineering Department, composed of skilled en- 
gineers, who are qualified to make plans and lay out work from archi- 
tect's drawings or sketches. The services of our Engineering Depart- 
ment are at the disposal of the trade at all times when desired for 
preparing heating plans for buildings of any character. We also 
prepare, if requested, a detailed estimate on the furnace and fittings 
necessary to install the work in accordance with plans thus made. 
This service many dealers find of material assistance in preparing bids, 
in further interesting customers and securing their contracts. Our 
plans are an excellent aid in erecting the work properly by furnace 
men of limited experience. We make no charge for preparing heating 
plans and estimates. 

The 300 Series Williamson Pipe Furnace has been developed as an 
answer to a constant demand for a furnace which combines all the good 
of the various furnaces made by the Williamson Heater Company 
during the past third of a century. It represents, therefor, the highest 
development of the pipe furnace, and its claim to superiority is fully 
borne out by exhaustive tests under every conceivable condition. 

We unhesitatingly claim for 300 Series the highest efficiency ever 
attained in a heater of this type, due to its unusual large radiating 
capacity and the amply and scientifically proportioned casing.

The Home ^ 

of the Williamson Line 

ON A FIELD of 26 acres in one of Cincinnati's most beautiful 
suburbs stands the Home of Williamson products. In that 
factory and by the men who here build, the name "Williamson" 
has become synonymous for quality, workmanship, and excellence of 
design.

Nor has such a position been reached through any spectacular 
growth or attempt to attract attention, but rather through years 
of conscientious and consistent labor to make Williamson products 
just a little better; to adapt all the proved, worthwhile ideas to 
their product, so that it will always embody all that is good in furnace 
construction, and to secure uniformity and standardization of manu- 
facturing methods by the use of molding machines throughout the 
factory, as well as many other work-saving devices. 

This is the largest factory in the country devoted exclusively to the 
manufacture of heating equipment. It is a well-known truism that 
it is not practicable to combine, in one factory, the making of furnaces 
and stoves. The methods and formulae differ. Furnace manufacture 
is now, and always will be, a highly specialized field. 

The mass of steel and brick and concrete called the Williamson plant 
is an expression of the enterprise and industry of the man who, during 
the past 30 years or more, has here built the furnaces that bear his name. 
And the world, always ready to acclaim merit, has beaten a path to 
The Home of the Williamson Line.

Williamson Flat Grate, May be shaken or 

dumped while standing and without 

opening ash-pit door. 




This grate is operated by a neat wooden 

handle which is always cool 

and clean. 




Williamson Triangular Grate. Easy 

to clean and shake. Very 

durable. 



Dustproof Grate 

The famous Williamson dust- 
proof dumping and shaking 
device has been embodied in 
this furnace, which means that 
it may be shaken and dumped 
when standing upright and 
without soiling the hands or 
clothes. It is also unnecessary 
to open the draft door during 
these operations, and no dust 
is therefore allowed to enter 
the cellar and work its way 
up into the rooms. 

The front is made in two 
pieces, extending to the top of 
the casing, and is so arranged 
as to be gas tight. 

Large Feed Door 

Firing is made easy because of 
the large feed door, and a 
recess is provided in the feed 
pouch for a water coil, so that 
hot running water may be ob- 
tained without interfering in 
any way with the operation of 
the furnace. 

Full Width Ash-Pit Door 

The ash-pit door extends the 
full width of the ash-pit, so 
that ashes may be removed 
from every part without diffi- 
culty. 

Only new iron is used in the 
manufacture of the 300 Series 
Furnace. Each purchase of 
raw material is carefully an- 
alyzed by an experienced 
chemist before being accepted, 
and the mixture is kept uni- 
form at all times. In other 
10 



THE WILLIAMSON HEATER CO., CINCINNATI, U. S. A. 



words, we are doing all that 
brains and science can do to 
manufacture a perfect, eco- 
nomical and durable furnace. 

Smoke Collar Extends 
Through Casing 

The smoke collar is of sufficient 
length so that it extends 
through the casing, and the 
smoke pipe is attached from 
the outside. This feature will 
be appreciated by those who 
have attempted to attach a 
new smoke pipe to one of the 
old-fashioned radiators with 
short collar requiring con- 
nection from the inside of the 
casing. 

Extra Large Casing 

Another feature is the extra 
large casing, which is from 4 
to 6 inches larger than most 
furnaces of similar sized fire- 
pot. The casings are lined 
with asbestos paper and corru- 
gated bright tin, there being 
an air space of about 1 inch 
between the corrugations. The 
bright tin reflects the heat and 
the air space and asbestos in- 
sulator prevent the outside 
from becoming overheated. 

The furnaces with even num- 
bers are those supplied with 
the flat grate, which, as ex- 
plained before, enables the 
housewife to shake or dump it 
without stooping or soiling her 
hands. Another advantage of 
this type grate is that only the 
clinkers and ashes on the outer 




Radiator is of great depth and capac- 
ity, and of a type with a highly 
satisfactory record. 




This Fire-pot is of the well-known two- 
piece corrugated type. Very 
efficient and durable.

edges fall into the ash-pit, while the good 
fuel in the center is not disturbed. In 
the case of the ordinary draw-center 
grate, the good fuel is dumped while the 
clinkers around the edges are untouched. 

Grates Interchangeable 

Those with odd numbers are equipped 
with the triangular bar grate, which is 
of exceptionally strong construction 
and a very satisfactory grate. A big 
feature is the fact that the two grates are interchangeable, so that the 
furnace may be used with either, and the change from one type to 
another may be effected within a few minutes' time and without 
dismantling. 

Gas Ring 

In states where gas is used for fuel, this 300 Series may be equipped 
as a combination gas and coal furnace by substituting a gas ring for 
the upper fire-pot section. This gas ring is supplied with pipe and 
mixer ready to attach to the gas supply. 

Large Capacity Radiators 

The radiator is of the horseshoe type, the upper and lower sections 
being fitted together with tongue and groove joints, which are cast 
against a chill. This insures a uniform casting, and, as the groove ■ 
is filled with asbestos cement before the two sections are bolted to- 
gether, a permanent gas and dustproof joint is insured. Another 
feature of importance is that the floor of the radiator slopes outward, 
which greatly reduces the resistance to the products of combustion 
as they escape from the dome section. 

Two-Piece Fire-Pot 

The 300 Series is equipped with a two-piece fire-pot that has proved 
through several years to be durable and satisfactory. The corruga- 
tions give it a large radiating surface, and the depth is such that it 
will keep fire for a long time. 

Large Opening into Radiator 

An important factor for efficiency is a large opening between the 
dome section and the 
radiator. In the 300 
Series with a 24-inch 
fire-pot this opening 
is 12 inches, and it is 
centered directly 

over the fire-pot. Gas Ring.

OUR No. 240 

FOR LARGE HOMES, SCHOOLS, CHURCHES, HALLS, ETC. 




This furnace is practically the same as the 300 Series, having similar ash-pit, fire-pot 

and feed sections, the only difference being in the radiator, which is of the middle joint 

type. 

We supply this furnace with the 30-inch fire-pot only, and it is particularly designed for 

very large residences, schools, churches, halls, stores, etc., in fact, any place where an 

extra powerful heater is required. 

The flat grate is of the same dustproof type as the 300 Series, and either flat or triangular 

grate may be specified.

OUR No. 75 



SOMETIMES a furnace is de- 
veloped that, through sheer 
merit, keeps its place in the 
front rank of the leaders in spite 
of improvements and the develop- 
ment of other types. 

This is true of the Williamson No. 
75 Furnace, which, on account of 
its extremely heavy construction 
and proved durability, is termed 
a heavy duty furnace. 

This type and size is especially 
adapted for use in schools, 
churches, stores and public build- 
ings where a heating system 
receives a great deal of abuse. 

Shipping weight, complete with 
casing, is approximately 2,885 
pounds. Heating capacity for 
public buildings is from 60,000 to 
80,000 cubic feet. The capacity 
for residence heating is from 1, 130 
to 1,400 square inches of piping.

Height of Casting 66 " 

Diameter of Firepot 29}/£" 

Diameter of Firepot 

Bottom 28M" 

Depth of Firepot 12 " 

Diameter of Grate 17 " 

The Grate is composed of two 
sections, a center round section 
which is operated by means of 
a yoke or wishbone-shaped cast- 
ing, and an outer ring section, 
operated by means of a clutch 



that engages and disengages by 
moving back and forth on the 
arm of the yoke. 

Special attention is called to the 
bell top directly under the radiator 
which alone weighs from 950 to 
1,000 pounds. This bell top has 
an enormous radiating surface, 
greatly increasing the efficiency 
of this heater. 

Ordinarily the products of com- 
bustion are carried into the radia- 
tor through a single opening, but 
in the case of the No. 75 Furnace, 
these are let into the Radiator 
through five tubes, thus securing 
perfect combustion and increasing 
the capacity of the Furnace. 

The Radiator is made of sheet 
steel with cast top and bottom 
heads. This method insures a 
quick response and efficient heat- 
n g with small fire. 

The No. 75 Furnace has been 
on the market in its present form 
for more than twenty years, and 
many dealers claim that it is thebest 
furnace ever made by the company. 

We have never received a com- 
plaint on the construction or 
heating capacity of this type. We 
therefore believe that we are 
justified in taking it for granted 
that it has met the most exacting 
demands imposed upon it, and 
we recommend it for the purposes 
to which it is adapted with this 
long record of satisfactory service 
and durability in mind.

WARMTH — Every room heated alike, every room cozily comfortable. Warmth — 
evenly controlled in all weather, ample on coldest days — unfailing, steady, 
perfect — in new homes or old, at about half the usual fuel expense. 
That is Homaker' s guarantee. 

And yet warmth is but the beginning of what this simple one-register heating plant 
brings you. That proud title, The Better Pipeless Furnace, was earned by the many 
vital improvements in Homager's design and structure that make for better health, 
greater economy and increasing comfort. 

By eliminating dust and dirt, Homaker keeps the air pure as well as warm. The handy 
shaker handle and wide ash-pit doors are examples of added conveniences. The pre- 
vention of heat waste brings remarkable fuel economy. And the entire sturdy con- 
struction means freedom from breakage or burning out. 

You shake and dump Homaker from an easy, upright position with all its doors closed 
tight. No trace of ash dust can escape. Outer casing and register both oversize; 
heat-radiating castings are centered; abrupt air passage angles eliminated. This 
combination effects freer warm air circulation. Quadruple casing, inner one with a 
heavy insulation of air-cell asbestos between the two sheets of steel. No heat wasted 
in the cellar.
